To determine if either of the given equations is a proportion, we need to check if the two ratios on each side of the equation are equal.
-
For the equation 168 = ?2412: We can interpret this as a proportion where we need to check if 168/2412 is equal to some other ratio. It's unclear what the values are supposed to be equated to, since there is a question mark in place of a = or a value.
-
For the equation 84 = ?126: Similar to the first equation, we need to look at the proportions.
We can clarify the equations a bit. Let's assume you mean:
- \( 168/2412 = ? \)
- \( 84/126 = ? \)
Now we will evaluate both ratios and check for equality.
-
For the first ratio:
- \( 168/2412 \)
- Simplifying \( 2412 \): \( 2412 = 168 \times 14.3571 \) (approximately).
- Thus, \( 168/2412 \) does not simplify to a clear ratio equal to anything that we can derive specifically.
-
For the second ratio:
- \( 84/126 \)
- We can simplify this: \( 84/126 = 2/3 \) since both can be divided by 42.
Since \( 168/2412 \) does not provide a clear rational number we can equate easily with something meaningful from the context given, while \( 84/126 \) simplifies down to a recognizable ratio.
Therefore, we can conclude that only 84 = 126 forms a proportion.
